BL45p Loss of Chassis Connectivity errors

Anyone ever seen these errors in the Integrated Management Log (IML) and have a solution?

Monitor IML for address or Serial number.
You can reseat all management modules and Update Firmware for all enclosures to 2.32
Reseat all management link cables, once you have connectivity loss for same enclosure swap management module around see if that make difference
I would not concern if it happened once in the while

Thanks for the quick reply, but I have swapped and switched the modules around already. We get a few of these messages every day and at different addresses. I will try to update to 2.32, as we are only running 2.30 at present.

If you have more than one power and blade enclosures, try to link them temporarily by skipping first day one enclosure than second, you might have problem with one of modules or signal backplane. You need to make identical cable 3ft long, as regular one too short.

We also had these errors on our BL20p G2's.
After we updated all of the HP firmware, this issue went away.

Hi SDRobinson,

we also had the same errors.
What PSP do you have installed?
What OS do you use?
Check your cables as Oleg71 said already.
If you use f.e. a HP SIM you can get the Serialnumber out of this tool.

We could easily identify the power modul causing the errors by looking into the eventlogs an then into HP SIM.

We upgraded PSP and then the firmware for the backplane and ILO.
After that teh errors did not apear angain.
